Description

Technical Field

[0001] The present application relates to the technical field of automated processing equipment, and in particular to a paper card opening mechanism and a paper card feeding device. Background Art

[0002] With the advancement of society, automated equipment is becoming increasingly commonplace in people's lives. When packaging various materials, such as bottles, cans, containers, reagent tubes, or boxes, in the pharmaceutical or food industries, into bulk boxes, mesh dividers are often placed inside the boxes to ensure proper placement and prevent damage from collisions during transport. These mesh dividers are also known as paper cards in the industry. Currently, most paper cards have folded and unfolded positions. During storage and transportation, the paper cards are kept in the folded position, forming a flat sheet that takes up little space and is therefore convenient for storage, carrying, and transport. After removal, the folded card is unfolded, creating a grid-like shape. Once the unfolded card is placed inside the box, materials can be loaded, with each item positioned using the card. However, in related art, paper cards are typically manually removed, unfolded, and placed inside the box, resulting in low efficiency, a low degree of automation, and high labor costs.

[0034] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0035] See Figures 1 to 3 , Figure 1 The figure shows a structural diagram of a paper card feeding device according to an embodiment of the present application. Figure 2 A structural diagram of a paper card opening mechanism for obtaining a folded paper card 300 according to an embodiment of the present application is shown. Figure 3 Shown Figure 2 Another perspective structural diagram of the structure shown. One embodiment of the present application provides a paper card opening mechanism 100, which includes: a mounting frame 110, a plurality of swing arms 120, a first power mechanism 130, and a transmission assembly 140. The plurality of swing arms 120 are arranged in sequence and rotatably disposed on the mounting frame 110. The swing arm 120 includes two grab arms 121 arranged at relative intervals. The two grab arms 121 are respectively arranged on opposite sides of the paper card 300 and can fix or release the paper card 300. The first power mechanism 130 is disposed on the mounting frame 110. The transmission assembly 140 is connected to the first power mechanism 130. All the swing arms 120 are connected to the transmission assembly 140. The first power mechanism 130 is used to drive the transmission assembly 140 to move, and the transmission assembly 140 can drive each swing arm 120 to rotate.

[0036] Please note that Figure 4 and Figure 5 The paper card 300 in this embodiment includes a plurality of first dividers 310 spaced apart in a transverse direction and a plurality of second dividers spaced apart in a longitudinal direction. The first dividers 310 and the second dividers are arranged crosswise and rotatably connected. The first dividers 310 and the second dividers cooperate to form a plurality of insertion holes for inserting materials. When materials are placed in the insertion holes, they are separated and neatly arranged within the packaging box.

[0037] During use, the aforementioned paper card opening mechanism 100 positions the two grabbing arms 121 of each swing arm 120 on opposite sides of a paper card 300 to secure it. The first power mechanism 130 then drives the transmission assembly 140, which in turn rotates the swing arms 120, thereby opening the folded paper card 300. After opening the paper card 300, it is then transported to the desired location. This automated paper card opening mechanism achieves high efficiency and low labor costs.

[0038] Because the multiple swing arms 120 are arranged in sequence and spaced apart, each includes two relatively spaced grabbing arms 121. The two grabbing arms 121 are positioned on opposite sides of the paper card 300 and can each secure or release the paper card 300. Thus, one grabbing arm 121 of each swing arm 120 is sequentially and spaced apart on one side of the paper card 300, thereby acting on multiple different locations on one side of the paper card 300, specifically, one side of the multiple first partitions 310. Simultaneously, the other grabbing arm 121 of each swing arm 120 is sequentially and spaced apart on the other side of the paper card 300, thereby acting on multiple different locations on the other side of the paper card 300, specifically, one side of the multiple first partitions 310. In this manner, driven by the first power mechanism 130, the paper card 300 can be smoothly and stably switched from a folded state to an open state, effectively preventing damage to the paper card 300 during the opening process.

[0039] See also Figure 6 and Figure 7 In one embodiment, the swing arm 120 further includes a connecting arm 122. The two grabbing arms 121 are connected via the connecting arm 122. The middle portion of each connecting arm 122 is connected to the transmission assembly 140. Thus, when the transmission assembly 140 drives the connecting arm 122 to rotate, the connecting arm 122 drives the two grabbing arms 121 to rotate synchronously. The grabbing arms 121 then drive the paper card 300 they grasp, thereby opening the paper card 300.

[0040] In one embodiment, the two grabbing arms 121 are connected to opposite ends of the connecting arm 122. The two grabbing arms 121 are rotationally symmetrical about the rotation center of the connecting arm 122. Thus, when the transmission assembly 140 drives the connecting arm 122 to rotate about its rotation center, the two grabbing arms 121 rotate with the same amplitude, thereby improving the stability of the paper card 300 when it is opened.

[0041] In this embodiment, the number of the swing arms 120 is the same as the number of the first partition plates 310. Figure 4 and Figure 5 As shown, there are five first dividers 310, and a corresponding number of swing arms 120. Each swing arm 120 has two grab arms 121 positioned on opposite sides of each first divider 310. During the paper card 300 opening step, each swing arm 120 synchronously rotates the corresponding first divider 310, thereby switching the paper card 300 from a folded state to an open state.

[0042] In some embodiments, the grabbing arm 121 includes, but is not limited to, methods such as negative pressure suction, magnetic attraction, snap-on connection, or clamping to secure or release the paper card 300. The specific configuration and arrangement can be flexibly adjusted based on actual needs and are not limited herein. In this embodiment, the grabbing arm 121 is specifically, for example, a suction arm that secures or releases the paper card 300 through negative pressure suction, thereby facilitating the securing or releasing operation of the paper card 300.

[0043] Based on the aforementioned embodiment, one end of the grabbing arm 121 is connected to the connecting arm 122, and the other end of the grabbing arm 121 is provided with a suction cup 1211. The paper card opening mechanism 100 also includes a vacuum generator 150 and a pressure gauge 160. The vacuum generator 150 is connected to the suction cup 1211. When the vacuum generator 150 is working, it can cause the suction cup 1211 to generate negative pressure, so that the suction cup 1211 can adsorb and fix the side of the paper card 300. The vacuum generator 150 can also inflate the suction cup 1211, thereby releasing the paper card 300. The pressure gauge 160 is used to detect the magnitude of the negative pressure applied by the vacuum generator 150, so that the staff can better control the operation of the vacuum generator 150.

[0044] Among them, the vacuum generator 150 and the pressure gauge 160 are both installed on the mounting frame 110. The vacuum generator 150 can be directly connected to the multiple suction cups 1211 through multiple air pipes, so as to realize the control of the negative pressure state of each suction cup 1211; the vacuum generator 150 can also be indirectly connected to the multiple suction cups 1211 through multiple air pipes, and for example, an air flow channel is formed on the grabbing arm 121, the air flow channel is connected to the air pipe in a one-to-one correspondence, and the vacuum generator 150 is connected to the suction cup 1211 through the air pipe and the air flow channel. Specifically, one end of the air flow channel is connected to the suction cup 1211, and the vacuum generator 150 is connected to the other end of the air flow channel through the air pipe. In this way, by setting the air flow channel on the grabbing arm 121, the length of the air pipe can be reduced, thereby simplifying the pipeline structure and reducing costs.

[0045] Based on the above embodiment, the adsorption arm is provided with an adsorption surface for attaching to the paper card 300. When the adsorption arm is provided with a suction cup 1211, the adsorption surface is the side of the suction cup 1211 facing the paper card 300.

[0046] See also Figure 4, the two adsorption surfaces of the swing arm 120 are spaced apart in a direction perpendicular to the adsorption surfaces. The size of the spacing is flexibly adjusted and set according to the thickness of the paper card 300 in the folded state. Specifically, the distance between the two opposite side surfaces of the paper card 300 in the folded state is D, the spacing is S, and 0.8≤S / D≤2. Optionally, S / D=0.8, 0.9, 1, 1.1, 1.2, 1.5 or 2. When S / D is less than 0.8, the two adsorption surfaces of the swing arm 120 are easily damaged during the process of synchronously clamping the two opposite side surfaces of the paper card 300; when S / D is greater than 2, the adsorption force of the two adsorption surfaces of the swing arm 120 on the paper card 300 is reduced, and the paper card 300 is easy to fall off.

[0047] See also Figure 6 and Figure 7 In one embodiment, the connecting arm 122 includes a first connecting segment 1221 and two second connecting segments 1222. The middle portion of the first connecting segment 1221 is connected to the transmission assembly 140, and the opposite ends of the first connecting segment 1221 are respectively connected to the two second connecting segments 1222. The two second connecting segments 1222 are arranged parallel to each other and are connected to the two grabbing arms 121 in a one-to-one correspondence.

[0048] Specifically, two opposite ends of the first connecting segment 1221 are respectively perpendicular to the two second connecting segments 1222 .

[0049] As some optional solutions, the connecting arm 122 can also be set to a regular shape such as a Z shape or an S shape or other irregular shapes, which can be flexibly adjusted and set according to actual needs.

[0050] In one embodiment, for any two adjacent swing arms 120, the two connecting arms 122 are arranged adjacent to each other in the vertical direction. A clearance portion 1212 is provided on the grabbing arm 121 of one swing arm 120 adjacent to the connecting arm 122. The clearance portion 1212 is used to clear the connecting arm 122 of the other swing arm 120. In this way, the transmission assembly 140 can drive the normal opening and closing movements of each swing arm 120 and prevent adjacent swing arms 120 from interfering with each other.

[0051] The avoidance portion 1212 includes but is not limited to an avoidance groove or a gap, etc.

[0052] See also Figure 2 and Figure 3 When the paper card opening mechanism 100 is in its initial position, the suction surfaces of the grabbing arms 121 on the same side of each swing arm 120 are in the same plane. Thus, the suction surfaces on one side of each swing arm 120 firmly hold one side of the paper card 300, while the suction surfaces on the other side of each swing arm 120 firmly hold the other side of the paper card 300.

[0053] See also Figure 2 、 Figures 4 to 6 In one embodiment, the first power mechanism 130 includes a first motor and a driving wheel connected to the first motor. The transmission assembly 140 includes a first transmission element 141, multiple transmission shafts 142, and multiple transmission wheels 143. The driving wheel and all transmission wheels 143 are connected to the first transmission element 141. Each transmission wheel 143 is correspondingly mounted on a transmission shaft 142, and each transmission shaft 142 is correspondingly connected to a swing arm 120. Thus, when the first motor is in operation, it drives the driving wheel to rotate, which in turn drives the first transmission element 141 to move. The first transmission element 141 can synchronously drive the rotation of each transmission wheel 143, which in turn drives the rotation of each transmission shaft 142. Each transmission shaft 142 in turn drives the rotation of each swing arm 120, thereby achieving the opening and closing of the paper card 300.

[0054] In one embodiment, the paper card opening mechanism 100 further includes a slide rail 171 and a slider 172. The slider 172 is mounted on the mounting frame 110 and slidably engages with the slide rail 171. The first transmission element 141 is a rack mounted on the slide rail 171. The driving wheel and the transmission wheel 143 are both gears that mesh with the gears.

[0055] Of course, as some optional solutions, the first transmission element 141 can also be set as a transmission chain, and the driving wheel and the transmission wheel 143 are both corresponding sprockets; the first transmission element 141 can also be set as a transmission belt, and the driving wheel and the transmission wheel 143 are both corresponding pulleys.

[0056] See also Figure 1 An embodiment of the present application provides a paper card loading device, which includes the paper card opening mechanism 100 of any of the above embodiments, and also includes a moving mechanism 200, which is connected to the mounting frame 110.

[0057] During use, the paper card loading device described above positions the two grabbing arms 121 of each swing arm 120 on opposite sides of a paper card 300 to secure it. The first power mechanism 130 then drives the transmission assembly 140, which in turn rotates each swing arm 120, thereby opening the folded paper card 300. After opening the paper card 300, it is then transported to the desired location. This allows for automated opening of the paper card 300, resulting in high efficiency and low labor costs.

[0058] See also Figure 1 、 Figure 8 and Figure 9In some embodiments, the moving mechanism 200 includes a first bracket 210, a second power mechanism 221, a third power mechanism 222, a mounting base 230, a second bracket 240, and a second transmission element 250. The second power mechanism 221 is mounted on the first bracket 210 and is provided with a first guide wheel 2211. The second power mechanism 221 is used to drive the first guide wheel 2211 to rotate. Similar to the second power mechanism 221, the third power mechanism 222 is mounted on the first bracket 210 and is provided with a second guide wheel. The third power mechanism 222 is used to drive the second guide wheel to rotate. The mounting base 230 is slidably disposed on the first bracket 210 along a first direction and is located between the first guide wheel 2211 and the second guide wheel. Optionally, when the specifications and dimensions of the first guide wheel 2211 and the second guide wheel are identical, the line connecting the center of the first guide wheel 2211 and the center of the second guide wheel is parallel to the first direction. The mounting base 230 is provided with a first tensioning member 231 and a second tensioning member 232. The second bracket 240 is slidably disposed on the mounting base 230 along a second direction, wherein the second direction is disposed at an angle to the first direction.

[0059] It should be noted that the first direction is Figure 8 As shown by the double arrow y in the second direction, Figure 8 As shown by the double arrow z in the figure. The angle formed by the first direction and the second direction includes but is not limited to 60°, 90° or 120°, etc., and can be flexibly adjusted and set according to actual needs. In this embodiment, the first direction and the second direction are perpendicular to each other as an example.

[0060] A third guide wheel 241 is provided on the second bracket 240 .

[0061] The opposite ends of the second transmission element 250 are connected to the second bracket 240. Optionally, the connection positions of the two ends of the second transmission element 250 and the second bracket 240 include, but are not limited to, being located at the bottom, middle, or top of the second bracket 240, and can be specifically set accordingly according to the arrangement position of the third guide wheel 241 on the second bracket 240.

[0062] In this embodiment, Figure 8 and Figure 9 As shown, the third guide wheel 241 is specifically disposed at the top of the second bracket 240, and the connection positions between the two ends of the second transmission element 250 and the second bracket 240 are correspondingly located at the bottom of the second bracket 240. In this way, compared to disposing the connection positions between the two ends of the second transmission element 250 and the second bracket 240 at other positions on the second bracket 240, the movement stroke of the second bracket 240 in the second direction can be greater.

[0063] The first guide wheel 2211, the second guide wheel and the third guide wheel 241 all abut against the inner side of the second transmission element 250, the first tensioning member 231 abuts against the outer side of the second transmission element 250 located between the first guide wheel 2211 and the third guide wheel 241, and the second tensioning member 232 abuts against the outer side of the second transmission element 250 located between the second guide wheel and the third guide wheel 241.

[0064] It should be noted that the inner side of the second transmission element 250 refers to the side of the second transmission element 250 facing the ring center formed by it, and the outer side of the second transmission element 250 refers to the side of the second transmission element 250 away from the ring center formed by it.

[0065] The second transmission element 250 is specifically configured to correspond to the first guide wheel 2211, the second guide wheel, and the third guide wheel 241. The first guide wheel 2211 and the second guide wheel can drive the third guide wheel 241 to move, thereby adjusting the position of the second bracket 240 along the first direction and / or the second direction. Specifically, when the first guide wheel 2211, the second guide wheel, and the third guide wheel 241 are all configured as pulleys, the second transmission element 250 is correspondingly configured as a transmission belt; when the first guide wheel 2211, the second guide wheel, and the third guide wheel 241 are all configured as sprockets, the second transmission element 250 is correspondingly configured as a transmission chain.

[0066] In some embodiments, a base 242 is provided on the second bracket 240. The base 242 and the third guide wheel 241 are respectively arranged at opposite ends of the second bracket 240. Optionally, when the base 242 is provided at the bottom of the second bracket 240, the third guide wheel 241 is correspondingly provided at the top of the second bracket 240. The base 242 is used to mount the mounting bracket.

[0067] During use, the second power mechanism 221 and the third power mechanism 222 work in a synchronized and coordinated manner. Specifically, when the second power mechanism 221 drives the first guide wheel 2211 in the same direction as the third power mechanism 222 drives the second guide wheel, the second bracket 240 can be driven to adjust its position along the first direction. When the second power mechanism 221 drives the first guide wheel 2211 in a direction different from the third power mechanism 222 drives the second guide wheel, the second bracket 240 can be driven to adjust its position along the second direction. In this way, driven by the second power mechanism 221 and the third power mechanism 222, the second bracket 240 can be driven to move and adjust its position along the first direction and / or the second direction, thereby enabling the second bracket 240 to adjust the position of materials along the first direction and / or the second direction. It can be seen that not only can the position of the second bracket 240 be adjusted more accurately, thereby accurately adjusting the position of the material, but also a large stroke adjustment position can be achieved. At the same time, three guide wheels share a second transmission element 250, which can cooperate with the work of the second power mechanism 221 and the third power mechanism 222. The structure of the device is relatively simple, the device cost is reduced, and it occupies less space.

[0068] Among them, since the second bracket 240 can accurately adjust its position along the first direction and / or the second direction, the second bracket 240 can drive the mechanical gripper on the base 242 to accurately adjust its position along the first direction and / or the second direction, so that the mechanical gripper can grab the material and drive the material to the target position.

[0069] In one embodiment, the mobile mechanism 200 further includes a controller. The second power mechanism 221 and the third power mechanism 222 are both electrically connected to the controller. The controller is configured to control the synchronous operation of the second power mechanism 221 and the third power mechanism 222. Thus, the second power mechanism 221 and the third power mechanism 222 operate in coordination under the control of the controller, resulting in a high degree of automation.

[0070] Specifically, the specifications and dimensions of the first guide wheel 2211 and the second guide wheel are consistent. The controller is used to control the second power mechanism 221 and the third power mechanism 222 to operate synchronously at the same speed, and to control the second power mechanism 221 and the third power mechanism 222 to operate in the same rotation direction or in different rotation directions.

[0071] In some embodiments, the second power mechanism 221 further includes a second motor 2212. The second motor 2212 is connected to the first guide wheel 2211. The controller is specifically electrically connected to the second motor 2212. Furthermore, the second power mechanism 221 further includes a first protective cover. The first protective cover is disposed outside the second motor 2212. The third power mechanism 222 further includes a third motor. The third motor is connected to the second guide wheel. The controller is also electrically connected to the third motor. Furthermore, the third power mechanism 222 further includes a second protective cover 2221, which is disposed outside the third motor.

[0072] See also Figure 8 and Figure 9 In one embodiment, the second transmission element 250 includes a first section 251 located between the first guide wheel 2211 and the first tensioning member 231, a second section 252 located between the third guide wheel 241 and the first tensioning member 231, a third section 253 located between the third guide wheel 241 and the second tensioning member 232, and a fourth section 254 located between the second guide wheel and the second tensioning member 232. The first section 251 is perpendicular to the second section 252, the third section 253 is perpendicular to the fourth section 254, and the second section 252 and the third section 253 are arranged parallel to each other. In this way, with the coordinated operation of the second power mechanism 221 and the third power mechanism 222, the second bracket 240 can be stably moved in the first direction or the second direction.

[0073] See also Figure 8 and Figure 9 In one embodiment, the mounting base 230 is provided with a third tensioning member 233 and a fourth tensioning member 234. The third tensioning member 233 abuts against the outer side of the second transmission element 250 and is located in the region between the first guide wheel 2211 and one end of the second transmission element 250. The fourth tensioning member 234 abuts against the outer side of the second transmission element 250 and is located in the region between the second guide wheel and the other end of the second transmission element 250.

[0074] In one embodiment, the second transmission element 250 further includes a fifth segment 255 located between the first guide wheel 2211 and the third tensioning member 233, a sixth segment 256 located between the third tensioning member 233 and one end of the second transmission element 250, a seventh segment 257 located between the other end of the second transmission element 250 and the fourth tensioning member 234, and an eighth segment 258 located between the second guide wheel and the fourth tensioning member 234. The fifth segment 255 is perpendicular to the sixth segment 256, the seventh segment 257 is perpendicular to the eighth segment 258, and the sixth and seventh segments 256 and 257 are arranged parallel to each other. Furthermore, the fifth segment 255 is parallel to the first segment 251, and the eighth segment 258 is parallel to the fourth segment 254. Thus, the second transmission element 250 forms a cross shape, which can stably drive the second bracket 240 to move in the first or second direction, ensuring stable and reliable operation of the second bracket 240.

[0075] In some embodiments, the first tensioning member 231, the second tensioning member 232, the third tensioning member 233, and the fourth tensioning member 234 are each independently adjusted and configured according to actual needs. In this embodiment, the first tensioning member 231, the second tensioning member 232, the third tensioning member 233, and the fourth tensioning member 234 are all configured as tensioning wheels, for example.

[0076] See also Figure 8 and Figure 9 In one embodiment, the first bracket 210 is provided with a first guide rail 211 extending in a first direction, and the mounting base 230 is provided with a first guide block 212. The first guide block 212 is slidably disposed on the first guide rail 211. In this way, under the guidance of the first guide rail 211 and the first guide block 212, the mounting base 230 can be stably moved in the first direction.

[0077] It should be noted that, only in order to be able to Figure 8 and Figure 9 Better display in Figure 8 and Figure 9 During the drawing process, the first guide block 212 is offset along the first direction relative to its actual position and deviates from the mounting base 230, that is, it is not connected to the mounting base 230. However, it should not be understood that the first guide block 212 is not connected to the mounting base 230 in the moving mechanism 200 of the present application.

[0078] In one embodiment, at least two first guide rails 211 are provided and spaced apart. Each first guide rail 211 is provided with at least two first guide blocks 212 . This allows the mounting base 230 to stably move along the first direction, thereby driving the second bracket 240 to stably move along the first direction.

[0079] As a specific example, two first guide rails 211 are provided, and the number of first guide blocks 212 corresponding to each first guide rail 211 is two.

[0080] Of course, as some optional solutions, the first guide rail 211 and the first guide block 212 are both provided as one, for example.

[0081] In one embodiment, the second bracket 240 is provided with a second guide rail extending in the second direction, and the mounting base 230 is provided with a second guide block slidably disposed on the second guide rail. Thus, under the guidance of the second guide rail and the second guide block, the second bracket 240 can be stably moved in the second direction.

[0082] It should be noted that, only in order to be able to Figure 8 and Figure 9 Better display in Figure 8 and Figure 9 During the drawing process, the second guide block is offset along the second direction relative to its actual position, deviating from the mounting base 230, that is, it is not connected to the mounting base 230. However, it should not be understood that the second guide block is not connected to the mounting base 230 in the moving mechanism 200 of the present application.

[0083] Specifically, the first guide block 212 is arranged on the side of the mounting base 230 facing the first bracket 210, so as to facilitate installation on the first guide rail 211; the second guide block is arranged on the other side of the mounting base 230, that is, the side of the mounting base 230 facing away from the first bracket 210, so as to avoid interference between the second guide block and the first guide block 212, and at the same time make the second bracket 240 and the first bracket 210 respectively located on opposite sides of the mounting base 230.

[0084] In some embodiments, to enhance the secure installation of the first, second, third, and fourth tensioning members 231, 232, 233, and 234 on the mounting base 230, the movable mechanism 200 optionally further includes a fixing plate 260. The fixing plate 260 is spaced apart from the mounting base 230. The fixing plate 260 is located on a side of the second bracket 240 facing away from the mounting base 230. The first, second, third, and fourth tensioning members 231, 232, 233, and 234 are also connected to the fixing plate 260.

[0085] In some embodiments, opposite ends of the second transmission element 250 are detachably connected to the second bracket 240 .

[0086] Specifically, both opposite ends of the second transmission element 250 are mounted on the second bracket 240 by, for example, a clamping manner. When the second transmission element 250 is damaged, the second transmission element 250 can be easily replaced.

[0087] See also Figure 1 Two clamping members 270 are respectively provided on opposite sides of the second bracket 240. The opposite ends of the second transmission element 250 are respectively clamped and fixed on the second bracket 240 through the two clamping members 270.

[0088] Of course, as an optional solution, the opposite ends of the second transmission element 250 can also be fixed to the second bracket 240 by fasteners such as pins, screws, rivets, etc.

[0089] In some embodiments, the second power mechanism 221 and the third power mechanism 222 are respectively connected and fixed to opposite ends of the first bracket 210. In this way, the movement stroke of the first bracket 210 along the first direction can be increased.

[0090] In the description of this application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0091] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, if the term "plurality" appears, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0093] In this application, unless otherwise expressly specified or limited, if a first feature is described as being "above" or "below" a second feature, or similar descriptions, this may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is described as being "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is described as being "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0094] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only embodiment.

[0095] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0096] The above-described embodiments merely represent several implementation methods of the present application.
